CM1200 port aggregation on 1/2 AND 3/4?

Working in tech support from home, I want to keep my lab/work network separate from the families. I run PFsense on an old PC for my router/firewall. The fam has the Asus RT-AC3100. I've had several occasions where I had to restart the modem due to changes I've made in my subnet needing some troubleshooting. I purchased the Netgear CM1200 Cable modem for the 4 Ethernet which I saw supported link aggregation (I pay for 4 IP's, may as well use more than the two I was).  Here's what I want to do...

 

Ports 1 and 2 --> PFsense --> HP Procurve managed switch 

     This will include LACP from PFsense to the HP Procurve for the LAN

 

Ports 3 and 4 -->Asus AC3100 -->(unmanaged switch)

      I know I cannot do link aggregation to an unmanaged switch. But I would like Dual WAN

 

Has anyone figured out a way to make Ports 3 and 4 be Dual WAN on the CM1200?

    Does not support dual WAN. 

     

    Have you tried putting the PFsence on port 1 and the Asus router on port 2? I have my CM1100 setup this way for two router support. LAG not enabled on the CM modem. Its working on my 1Gb ISP network.
